Referr ng more indeta l to the drawings are - ,v pre-sent lnstance signifies the crank case of an internal coinbnstionengine. This casing asn'sual houses ,thec'rank shaft and the connected .pi'tnien of the pistons. Within this crank c'a'se 'a constant level of oil is maintained 'at a point indicated by the dotted line AA.

To supply the crank cases I with the heoess'iry mbunt of oil the follow- 7 ing brovisioii is made. 7

To the side at the ei'zink case, and in having eiongeted bodvportion designated j tiiig within the age-many threaded xfim i of the extension 4.

sion 4 is a fluid conduit illustrated at 6. This conduit is provided with an outlet aperture 7 and terminally ends in a threaded extension 8, which extension passes through the aperture5 in the upper end ofthe chamber. Threadedly engaged on the extension 8 is a nut illustrated at 9, which nut is locked in position by superimposed nutted member illustrated at 10. Engageable with the threaded extension 4 of the chamber is a stuffing gland designated 11 between which gland and the terminal endofthe threaded extension 4 is interposed a suitable packing designated 12. This stuffing gland together with the packing constitute a stuffing box to prevent the escape ofoil between the side walls of the conduit 6 and the interior'wall The oil sn 3 'Jl reservoir as in all svsteins l y 7 it.

of the character under consideration is posi-' tioned at any point on the vehicle or structure above the level point of the engine casing 1 and from this oil reservoir the lubricant is conducted by a pipe illustrated at 13. This pipe 13 is usually of a flexiblecharacter so as to permit a slight bending thereof without impairing the passage therethrough. This pipe 13 leads from the reservoir to a float chamber which will now be described.

The float chamber is constructed of a body portion illustrated at 14 and a cover therefor designated at 15. The body portion of the float chamber is provided with a laterally extending recessed portion designated 16. One side wall of this laterally extending portion 16. is threadcdly tapped as at 17 while the opposite side wall is provided with a socketed recess 18. A bearing pin having a smooth portion 19 and a threadedenlarge ment 20 is adapted to be. positioned within the corresponding portions 18 and 17 just mentioned. The bearing pin has a nutted head as at 21 to permit the manipulations thereof. WVhen the bearing pin is in position the smoothed portion thereof spans the space between the side walls of the laterally extended portion of the float body 14. ithin the float body 14 there is also positioned afloat 22, which float may be of any usual construction now on the market. Pivotally supportedupon the smoothed portion 19 of r the bearing pin is a strap member designated 23, which strap member is terminally secureda-t its free end to the float 22. The upper edge of thelfloat body 14 is provided with aseries of threaded bossesdesigna'ted 24-1-24 for a purpose hereinafter described. 4 ,The cover for the float body is cor respondingly shaped to the outlines of the upper edge of the float body 14 and is therefore "provided with an extension designated 25 whichcovers the recessed portion 16 in the float body. Extending upwardly from the cover.15 is a bossed extension illustrated at '26 which terminates in an externally threaded portion 27. The bossed extension 26 as well as the extension 27 is provided with a passageway 28 which passageway is enlarged at its point of passage through the bossed extension 26 as shown at. 29. This point of enwith the valve seatx The lower face of this valve plug 30 is adapted to rest against the upper surface of thexstrap member-23 witha in' the float body 14, whenthe cover 15 is secured in its operative position. In order to hold the cover member 15 firmly in its operative position the said cover member 15 1s provided with a series of' peripherally arranged holesor passages designated 31, through which holes suitable binding elenients designated 32 are adapted to pass and threadedly engaged withinthe bosses24 in the upper end of the float body 14.

r The pipe 13 is suitably connected to the extension 27 through the. employment of a coupling generally illustrated at 33 which threadedly engages over i the threaded extension 27. A suitablevent opening 34 is also provided in the cover 15, which vent opening freely permitsthe backing of the oil up into the float chamber when the engine or the operative part thereof is broughtsto a standstill, I r

As shown in the drawings the conduit (3 is ofa general U -shaped form andis provided with an externally threaded flange 35 which is adapted to fitwithin a bottom" opening in the float body 14 and firmly anchored therein by a. nutted member 36, the side portions of which are adapted to rest against the interior surface of the body 14. To prevent the escape of oil at this point of connectionany externally aperture designated 38, which aperture is normally sealed or closed by the threaded plug 39. V i

' For the purpose of further understanding the invention, let us assume that the attachment is in applied position to the crank case of an internal combustion engine and that the amount of oil within the crank case'hasbeen found to be insufficient to properly enable the movable parts of the engine to effectively splash the oil and thereby lubricate the en- 7 closed bearings. If such is the case the oil level within the crank case is raised simply by turning on the nutted member 9 which raises the conduit 6 softhatits outlet end 7 is further drawn into the chamber secured to the'side of the engine casing l. It will of V v tlie oil'through the conduit fi'so that the flow is maintainedslightly ab ve me outlet v end 7 of said cornd ii t' dwliis verficaladWstfloatchamber and its valvular parts asotiiat the' level of the oil crank case is raised according to this----vertical Whenever the engine is brought to a standstill the oil films which are upon the movable parts of. the engine structure, will drain back into the crank case and'thereby' effectively raise the level thereof. This surplusamount of oil willbe permitted to accumulate above the outlet end of the conduit 6 and should any heavy particles be carried by this oil they will be effectively trapped by reason of the fact that the outlet end of the conduit 6 is above the lower 'wallof the attached chamber. If by chance any of these particles should enter the condu1t16 they will be retained within the lower run thereof and thereby prevented from entering the float chamber and. interfering with the operation of the valvular parts thereof.
